Flammable hydrocarbon samples can be measured at very low levels with our Flame Ionization Detector (FID) sensors. Based around the detection of ions formed by combustion, they are key to the sensitive, accurate measurements delivered by our SERVOPRO Chroma, FID and HFID analyzers.
FID sensors are designed to measure flammable Total Hydrocarbons (THC) down to parts-per-billion (ppb) levels.
They work by detecting ions formed in the combustion of organic compounds in a sample, producing charged molecules that cause electrical conduction between two electrodes.
The ions are attracted to a collector plate and induce a current upon hitting the plate. The FID measures this conduction and produces an output which is directly proportional to the concentration of THC in the sample.
This signal is then enhanced by a logarithmic amplifier that reduces drift and thermal noise, delivering an accurate, nondepleting measurement with 100ppb resolution.
FID can be used with Gas Chromatography techniques to provide trace gas measurements for a wide range of applications. Some carbon-containing compounds, and a number of gases of common industrial interest, fail to significantly ionize in a flame and so are either undetectable or may not be effectively measured by the FID.
Air separation units
Product pipelines
Cylinder filling stations
Decreased drift and thermal noise
Accurate, non-depleting measurement
Resolution of 100ppb
Industrial processes where THC contamination is possible, such as air separation units, product pipelines, and cylinder filling stations.

The Chroma is optimized to specific background gases to ensure optimum performance for your application.
With trace analysis capability, the FID is ideal for ASU safety and quality control applications.
Utilizes an internally heated oven set to 190°C (374°F) to maintain the sample gas above its dew point, for optimum performance in total hydrocarbon analysis (THC).
